revolve Rotate a sketch around some provided axis, creating a solid from its extent. manual

Rotate a sketch around some provided axis, creating a solid from its extent.

This, like extrude, is able to create a 3-dimensional solid from a 2-dimensional sketch. However, unlike extrude, this creates a solid by using the extent of the sketch as its revolved around an axis rather than using the extent of the sketch linearly translated through a third dimension.

Revolve occurs around a local sketch axis rather than a global axis.

You can provide more than one sketch to revolve, and they will all be revolved around the same axis.

revolve(
  data: RevolveData,
  sketches: [Sketch],
): [Solid]

Arguments

Name Type Description Required
data RevolveData Data for revolution surfaces. Yes
sketches [Sketch] Yes

Returns

[Solid]
